Overview

Column

This dashboard summarises analysis of one microsecond molecular dynamics simulations of five conditions:

  1. 3VRI, HLA-B*57:01-RVAQLENVYI in complex with abacavir
  2. 3VRI, minus peptide
  3. 3VRI, minus abacavir
  4. 2RFX, HLA-B*5701, presenting the self peptide, LSSPVTKSF
  5. 2RFX, minus peptide

The summary dashboard shows:

  • Pictures of the two different abacavir conformations observed in condition 2.
  • PCA A: The conformational landscapes defined by the major collective motions, these are the contour plots indicating how many distinct populations were observed during 1 microsecond simulations. (The motions were calculated using C-alpha atoms only).
  • PCA A: Graphs of the extent of each of the first 20 major motion contribution to the overall motions i.e. the percentage of variance.
  • PCA B: Animations of the top two collective motions PC1 and PC2, together accounting for around 50% of total motions in each case.
  • Residue Flexibility: Graphs of the residue root mean square fluctuations i.e. how much each residue moved relative to its average position, and therefore a measure of the relative flexibility of each residue in the protein under each condition.
